| 摘 要：分别用加速溶剂萃取法（ASE）和固相微萃取法（SPME）对南沙参进行提取，通过气质联用（GC-MS）对南沙参的挥发性成分进行定性和半定量分析，从ASE萃取物中检测出61个组分，占其总出峰面积的84.28%；从SPME萃取物中检测出39个组分，占其总出峰面积的90.36%。二者相同组分18个，分别是：2-正戊基呋喃、己酸、正辛醛、壬醛、正壬醇、正辛酸、硬脂酸甲酯等。ASE除了萃取低沸点的萜类外，还有高沸点酸类、萜类、醛酮类和大极性醇类。而SPME萃取的物质主要是低沸点的萜类、醛酮类和小极性的烃类。两种前处理方法一起用于南沙参有效成分的提取，可以得到更全面的信息。 |

| Abstract：Volatile components were extracted from Radix adenophorae using accelerated solvent extraction（ASE）and solid phase micro-extraction（SPME），and were qualitified by gas chromatography-mass spectrometry（GC-MS）. Results showed that 81 compounds were identified，61 components accounting for 84.28% in Radix adenophorae were identified by ASE and 39 components accounting for 90.36% in Radix adenophorae were identified by SPME. There were 18 common components which are 2-pentylfuran，hexanoic acid，n-octanal，heptanol，nonenal，n-nonylalcohol，octanoic acid，methyl stearate，et al. ASE can extract the substances such as acids. terpenes，aldehyde ketones and the big polar alcohols with low boiling point as well as the high boiling point. But SPME was suitable to extract the substances such as terpenes，aldehyde ketones and small polar hydrocarbon compound with the low boiling point. The two pre-treatment methods can be used to extract the substances together in order to acquire full information. |
